JUST installed Konis on my 94 ATX. Goes to alignment shop this AM.
You'll most likely need the stock tubes to cut down for the Konis.
Any yard should have some. You'll need a cut off tool to shorten them up.
Pipe cutters will work for the front but you'll need a cut off wheel for the rear. (No clearence for the Pipe cutter. I used a saws-all). When using the pipe cutter you will also need a dremel-type grinding wheel to grind the lip
off the inside of the tube ($3-4.00 at the parts store).
The fronts are a bit of a chore as my tubes are 48mm and the Konis are
45mm. A spacer is supplied and it is a REALLY tight fit. A press is definately
recommended here. You can use a hand sledge on the bottom of the casing like I did but you'll produce a lip that needs to be ground off before you can get them in the knuckle.
